The invention relates to a cabinet or rack body, in particular for receiving drawers or sliding shelves according to the preamble of claim 1.

Such a cabinet body is known from DE-OS 1778 700.

5 The transverse supports carried over the space between the wall elements are formed by angular rails provided in pairs, which are formed at the ends with bent lugs. The front and rear edges of the wall elements are applied to U-shaped profile rails, which are formed in the entire length with cut-outs. A two-way locking device between transverse carrier and wall element is provided, on the one hand, by the latches at the ends and on the other side of cutouts, the latches being inserted into the cutouts, firstly connecting the two wall elements, second, supports are provided for the intermediate shelves.

However, if a cabinet or rack is assembled according to the above-mentioned printing without inserting the intermediate shelves provided, it is obtained that the two wall elements are connected to each other by force transfer, a displacement towards each other being considered to be excluded, but a locking, however, which may prevent a parallel-lellogram-like, angular tilt, is not provided. Accordingly, such a cabinet or shelf is only slightly stable in shape, at least as long as no back wall is fitted, and thus is not suitable as a furniture body open to both sides, or as a furniture body capable of accommodating drawers.

It is therefore the object of the invention to further develop a structure according to the preamble of claim 1 such that two flat wall elements are simply connected and power-resistant and spring-stable by means of transverse supports, in a simple manner and using the least possible number of building elements, to provide an inherently stable structure. , especially against 35 tilting and edging resistant connection which may act as cabinet or shelf body which is open to

both sides, ie without back wall ,, and which is arranged for picking up drawers. The stated object is achieved with a cabinet or rack body of the type initially referred to, which according to the invention is peculiar to the design according to the characterizing part of claim 1.

The locking means according to the invention makes it possible to achieve that the wall elements support each other in a bending stiff manner, the first locking elements e.g. may be integrally formed with the wall element 10 and act as supporting arms, which in turn are connected to the bending pins of the associated transverse supports. It is particularly advantageous if the supporting surfaces of each locking member are arranged approximately perpendicular to the plane of a wall element as well as in pairs opposite to each other. Thereby a bending rigid locking compound is obtained, the components of which are readily inserted into the cross-sectional height of the cross-member.

This increases the space utilization rate.

Preferably, each cross member is attached to each wall member, each having a locking connection at both ends. In principle, however, cross-beams with a larger cross-sectional width may also be considered, such as for example. plate-shaped and bending rigid transverse supports, covering a greater portion of the width of the wall elements disposed on both sides and each provided with 25- more locking connections at both side edges. Such plate-shaped, bending rigid transverse supports can especially be used as carrying shelves without drawers. In this way, it is possible to build stand bodies of simple design, even with a large number of spaces.

30 In principle, of the locking joints provided at each side edge of such a plate-shaped cross-carrier, only one needs to be bending rigid, and that only for one of the side edges, while the other locking joints act only as anchoring the cross-member to the puller. - and shear forces relative to the wall elements. However, the cabinet body gets an optimum

stiffness and shape resistance if all locking joints are bending rigid.

According to a further development of the cabinet or rack body according to the invention, at least two transverse supports 5 with corresponding locking elements are arranged on a line running parallel to a drawer or drawer space plane, and can optionally act as a support and guide for drawers. In that case, it is generally advantageous if the supporting surfaces of the first and second locking members are arranged parallel to the drawer or drawer space plane. This measure provides a relatively low height of the connecting elements.

By designing the first locking elements as parts of a carrier strip extending parallel to the drawer or sliding shelf plane, not only a simplification of the design and thus the manufacture of the carrier strips is achieved, but it is also made possible without any special material or work effort. to place a greater number of transverse carriers on such a carrier list without the need to design special locking elements for each connection point. In this connection, it is preferred that in one piece with one wall element, a support strip is formed which is formed as a stiffening rib and extends at least the predominant part of the width of the wall element, thereby providing both a stiffening and sufficient spacing between the connection points with the individual transducers.

In principle, the anchoring of the cross supports to the wall elements against tensile forces in the longitudinal direction of the cross supports can be achieved in a force-dependent manner, ie. by a sufficient squeezing and holding friction between the support surfaces of the first and second locking members. In that case, it is preferred that the mutually opposite supporting surfaces of the complementary locking elements incline at an acute angle 35 to form a self-locking wedge connection within each locking connection. The composition of such a compound

compression can be done simply by compression, generally manually without the use of special tools.

An important further development of the invention relates to the placement of drawers or shelves of relatively small height within the cabinet body. Such low firing elements, which also e.g. may consist of plate-shaped sliding shelves without side framing, optionally with recesses for placing small parts, would, if placed over one another in larger numbers, would require a relatively large total cross-section of the enclosure space when mounted on bend-fetish transverse supports. cause an undesirable loss of useful volume. This further development of the cabinet or rack body according to the invention comprises - generally in addition to at least one bending rigid transverse carrier - at least one transverse member, which is soft elastically flexible in its center region, and which is secured to the wall elements on the two mutually opposite end portions. pages using locking links. This soft resiliently flexible design allows a very small cross-sectional height 2Q and thus a little extra space requirement, since the drawers are mounted and supported on the end members of the cross members which are in direct communication with the wall elements through the locking connections. Thus, the flexibility of the cross members does not interfere with the uptake of the 25 weight of the drawers. The corresponding relief of the middle part and thus of the entire transverse member from load-related bending moments. is obtained automatically by the interaction between the vertically rigid locking joints and the vertical compliance of the middle member of the cross member.

3Q The soft elastic flexural design of the transverse members makes it possible to mount the transverse members in an already assembled body in a particularly advantageous manner.

To this end, a transverse member is made shorter by deflecting manually from its planar shape so that it can be easily inserted within the interior width of the cabinet. It is now possible to insert on one side of the cabinet the end part of the cross member

DK 153518 B

in the recesses of the locking means in the wall elements, whereby the insertion into the recesses in the opposite wall element takes place by releasing the elastic deformation of the transverse member and returning to its planar shape. The corresponding soft flexibility is obtained in a particularly simple manner in an embodiment in which the cross member plate body in its center region exhibits a bearing cross-sectional length which is reduced relative to the two end portions. Incidentally, for this mounting method, a flexibility or flexibility, respectively, is sufficient. compliance with transverse forces compatible with the carrying function associated with the uptake of lighter items to be placed in drawers or on shelves. Thus, the said transverse means may even be used as carrier shelves without any drawers or shooting shelves.

Another important embodiment of the cabinet or rack body according to the invention is characterized in that at least one receptacle is open in two mutually opposite directions, e.g. for drawers and / or sliding shelves, is formed by means of at least one bending rigid transverse carrier and / or at least one soft elastic flexible transverse member together with wall elements for both sides. One or more of such drawer spaces, open in mutually opposite directions, permit the arbitrary utilization and operation of the cover or rack from both mutually opposite sides. In that case, these spaces can be utilized for two-sidedly accessible placement and storage of objects, or for transferring objects, such as the documents or other papers, from one side of the cabinet or stand. Such use proves particularly useful in bulky cabinet or rack arrangements, such as for example. cabinet or tripod walls arranged between two opposite workstations. Incidentally, such a space, open to two mutually opposite sides, may optionally be used for insertion of mutually opposite half-shovels.

DK 153518 B

Also, an important advantage lies in the fact that, with respect to the opposite sides, the symmetrical design of the cabinet or rack body allows the arbitrary use of drawers with operation from one or the other side. For example, in a flexible way, the different needs for locker or rack space are taken into account at two opposite workplaces.

Thus, overall, a significant extension of the field of application has been achieved and an improvement in adaptability with respect to different conditions of use.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the exemplary embodiments of cabinet or rack bodies according to the invention and 15 parts thereof. 1 is a front view of part of a cabinet body; FIG. 2 is a vertical section through a cabinet side wall along line II-II of FIG. 1, FIG. 3 is a vertical sectional view through the side wall along line III-III of FIG. 2, FIG. 4 is a horizontal section through a wall element with transverse supports fitted along section line IV-IV of FIG. 1, FIG. 5 is a vertical sectional view through a wall element of a modified configuration; FIG. 6 shows a transverse carrier, seen in view V in FIG. 4, FIG. 7 is a cross-section through the transverse carrier along line VII-VII of FIG. 6, and FIG. Figure 8 shows, in a plan view, a plate-shaped 30 soft elastic flexible cross member with locking means with the wall elements on both sides.

According to FIG. 1 and 2, the cabinet frame consists of two-sided wall elements WE with transverse supports QT, which are connected at their ends by snap joint locks RS to support strips TS 35 for the wall elements. In the example shown, the cross supports

in the embodiment of FIG. 2 at the same height relative to the drawer plane E-E as well as mutually parallel and spaced within the locker compartment, so that the two wall elements support one another in a rigid and extremely firm manner.

Between the opposite pairs of transverse supports as well as at the top of the upper transverse carrier - a pair of drawers FC is formed at each location for receiving a drawer. These drawer spaces are open against the opposite edge sides ST, and have the same continuous internal cross-sectional height. The drawers can thus be optionally inserted from both sides. Furthermore, as a whole, the cabinet frame is designed symmetrically with respect to the opposite oriented edge sides ST, so that there is no restriction on the positioning of the service side of the drawers. It is also possible to use mutually opposite half drawers, which are not shown in the drawing. By means of plate-shaped transverse beams, which will be referred to below, or by means of the already mentioned, plate-shaped and bending rigid transducers, it is possible to provide the drawer compartments FC with closed floor or bottom surfaces. Thereby, there are shelves which are particularly useful for placing small objects, which shelves of choice can also be used to carry drawers.

In FIG. 1 and 2, on the lower transverse plane plane, is a schematic arithmetic a drawer S, the height of which corresponds to the distance between superposed transverse carriers and supporting rails, and which, with its side edges projecting downwards 30 below the drawer bottom, rests on the supporting rails TS. This ensures a safe guide to the drawer, even when it is pulled relatively far.

The lower end of the cabinet frame is formed solely by the transverse supports, while the upper side is closed by a cabinet frame 35 placed on top and as in FIG. 1-3 are only partially anti-8

that. For this purpose, at the top of the wall element is OK

and in one piece with this, a carrier flange AS is formed which transversely of the wall element projects inwardly into the cabinet frame and is provided with a list-shaped, upwardly-extending first abutment member ASO to ensure the mutual position of the superposed cabinet frames. On the underside of the upper cabinet frame and - as a result of the uniform design - also at the corresponding location on the lower cabinet frame, a complementary, second impact member ASU is designed simply as part of the inner surface of the bearing list TS. Each pair of such first and second abutment members forms on the one shown in FIG. 1 and 2, an abutment connection with locking in two mutually perpendicular horizontal directions is obtained, whereby the two cabinet frames are mutually positioned on all sides. It will be appreciated that, when setting up a single cabinet frame, a suitable cover plate, not shown, may be used to close the cabinet frame upward, possibly provided with impact members of the same kind as the said 2Q other impact members ASU.

A similar interconnection and reciprocal positioning option is also available for side-by-side cupboard frames. For this purpose, as shown in FIG. 1 on the individual support strips TS and 25 on the opposite surfaces of the wall elements WE formed notes NT. The notes NT extend within the cross-sectional height and length of the support strips, so that the support strips thereby constitute U-beams having a corresponding cross-sectional height and a large bending strength in their connection-3Q with the plate body of the wall element. In the notes NT, on the one in fig. 4, position locking means LS which engage corresponding notes in the adjacent cabinet frame. In order to improve the stiffness of the wall element 35

ISLAND

In the plate body of the notes, the notes NT are provided with cross bridges QS, which are distributed along with the notes. In addition, the notes in the manufacture of the wall elements by compression or injection molding of plastics show the advantage that material accumulation with the consequent risk of cooling shrinkage and surface deterioration is avoided.

As can be seen from FIG. 1 and 3, the carrier strips TS exhibit a cross-sectional height which decreases with increasing distance from the surface of the associated wall element, i.e., because of the U profile mentioned. towards the interior of the cupboard, and with its protruding longitudinal edges they form a plate-shaped portion PL, extending over most of the length of the carrier strip, cf. also fig. 4. This plate-shaped part is suitable for its full length to function as a connecting piece or convex connecting element for connecting transverse supports. In the example shown, only the end portions of the plate-shaped support member PL located on both sides are formed as first locking member REX for engagement with corresponding second locking member REV on the ends of the cross-beams.

FIG. 5 shows how it is possible to provide a wall element WE 1 with support strips TS 2 on both opposite side faces. The front view of the figure shown in this figure shows a region of the wall element with 25 mutually opposite and at the same height, supporting beams TS1, whose cross-sectional shape is simplified in relation to the supporting strips TS in the embodiment described above, and which essentially consists only of of a plate-shaped support strip portion PL. At the front and back of this carrier list part 3

at the end ends, a first locking element REX is again formed

as in the above embodiment. In both embodiments, at the first locking element REX, stiffening ribs QV are formed, partly on the wall element and partly on the support strip part PL. This increases the bending strength, both 35

10 o of the carrier strip part PL and of the locking element REX. This is particularly important for the one shown in FIG. 5, because in order to avoid material accumulation, the carrier strip TS is designed as a relatively narrow and thin strip, which in itself has a certain bending stiffness. To support and guide the drawers in the area between the transverse supports QT, the support frame TS1 can be further formed with a relatively narrow molding set P. By using wall elements with support strips on both sides, it is easy to assemble a multi-compartment cabinet frame.

The transverse supports are in the manner shown in FIG. 6 and 7 are designed as U-profile bodies with stiffening cross ribs V, thereby increasing the bending strength and bending stiffness.

15 The transverse members form the end portions of the interior of the profile in the manner shown in FIG. 4 with their open profile sides facing towards the interior of the cupboard and pressing on the connectors or the first locking elements REX. Owing to a not shown angular orientation of the supporting surfaces TRX and TRX respectively facing each other. TRV on the locking elements REX respectively. The REV achieves an automatic clamping action in the assembly means, thereby providing a secure wedge connection between the transverse supports and the wall elements. It will be appreciated that the support pairs always coincide at an acute angle to the direction of insertion of the cross members, with reference to FIG. 4 always always facing outwards from the interior of the cabinet and parallel to the plane of the wall elements WE.

As shown in FIG. 2, the locking elements REX are thereby arranged along a line X-X extending with the drawer plane E-E, so that the transverse supports are also placed at the same height with respect to the drawer plane and thus form part of the overall support surface for supporting the associated drawer. The use of portions of the plate-shaped part PL on each of the support strips TS as locking means means that the collecting means are also arranged parallel to the drawer plane and can therefore have a relatively large width.

u DK 153518B

extent. Although the locking elements REX have a relatively small cross-sectional height, in this way sufficient bending strength and bending stiffness are obtained.

In addition, the illustrated embodiment 5 includes a molded anchorage of the transverse supports in the wall elements with respect to forces along the axis of the transverse supports. To this end, undercuts HS are designed to have undercuts HS in which form-locking members VR intervene on the ends of the cross-members. These locking members are simply designed as end walls in the U-profile of the cross support and therefore require no further shaping effort.

FIG. 1-3 also hint at an intermediate shelf ZF located within the height distance between 15 two transverse supports QT and associated supporting strips TS in the form of a relatively thin-walled transverse plate QR. To connect these transverse plates to the wall elements, locking connections RA are provided, which consist partly of sectional projecting edge regions KT of the transverse plate and partly of corresponding recesses AN in the inside of the wall elements.

The mounting of such a non-bending rigid intermediate bottom in the composite cabinet frame is already discussed in the introduction.

FIG. 8 shows a simple possibility of adjusting the suitable bending softness 25, since the cross-sectional length of the transverse plate as a measure in the direction of insertion is reduced in the middle region relative to the edge regions. Instead of the present contour narrowing, a corresponding recess or cutout may be used. However, the narrowing of the transverse plate's depth dimension around its center axis, as indicated in the example, results in the substantial advantage that no part of the drawer can be collided with the parts of the leading edge VK which consequently incline with respect to the axis or the direction of introduction of the drawer. and

ISLAND

any transverse or downwardly projecting transverse edges. In the event of any bias or skew in the cabinet frame, due to the flexibility of the transverse plate, some bending of this up or down may have to be expected, which could cause such collisions. The present contour, on the other hand, forms slightly rising incline edges, which can be easily overcome, even when inserting drawers with transverse edges on the underside. The same applies to the 10 rear edge HK with respect to the pull-out of the drawer, and also to the insertion movement in cases where in one and the same Drawer space are mutually opposite half drawers.
